Michael record the number of miles he runs each week for the nine weeks 6,11,13,8,15,9,11,5,9 which box plot represents the data
Five number summary
min = 5Q1 = 7median = 9Q3 = 12max = 15===============================================
Explanation:
The given list of values is {6, 11, 13, 8, 15, 9, 11, 5, 9}
It sorts to {5, 6, 8, 9, 9, 11, 11, 13, 15}
The middle most value is the second 9. We have four items below or at the median {5,6,8,9} and four values above the median {11,11,13,15}
The middle item of {5,6,8,9} is (6+8)/2 = 14/2 = 7. This is the value of Q1.
The middle item of {11,11,13,15} is (11+13)/2 = 24/2 = 12. This is Q3.
The min is 5 since it is the smallest of the original list.
The max is 15 because it is the largest of the original list.
The five number summary is
min = 5Q1 = 7median = 9Q3 = 12max = 15The boxplot that matches with this five number summary is the boxplot in the upper right corner.
The min is the left whisker. The max is the right whisker.
The left edge of the box is Q1. The right edge of the box is Q3.
The middle vertical line inside the box is the median.
Answer:
upper right corner

Solve the system of linear equations using multiplication. - 3x + 2y 5x - 3y = 17 The solution is
Answer:
Required Answer:-
Given:
5x - 3y = 2
3x - 2y = 4
To Find:
The values of x and y.
Solution:
We have,
→ 5x - 3y = 2 – (i)
→ 3x - 2y = 4 – (ii)
Multiplying equation (i) by 2, we get,
→ 10x - 6y = 4 – (iii)
Multiplying equation (ii) by 3, we get,
→ 9x - 6y = 12 – (iv)
Subtracting (iii) from (iv), we get,
→ -x = 8
→ x = -8
Now, from (i),
→ 5 × (-8) - 3y = 2
→ -40 - 2 = 3y
→ -42 = 3y
→ y = -14
So,
→ (x, y) = (-8, -14)
Answer:
(x, y) = (-8, -14)

Please help and look at the image. (The table shows the transportation method of employees at a certain company. What percent of the employees walk to work?
)
Answer:
0.5% to walk to work.
Step-by-step explanation:
First, find town many employees in total, Add all the numbers to find it. We get 1400, next we find the percentage of 1400 that gets us the number 7.
0.5% of 1400 is 7 so 0.5% is the answer :)
Kim creates a model of a building. The scale of her model building is 1 foot to 8 inch. Some of the measurements are shown in the table. 11 Enter numbers in the empty boxes to correctly complete the table.
Answer:
Left
50 feet
Right
16 inches
10 inches
Step-by-step explanation:
Here, we want to make a conversion and fill in the empty spaces
The scale is 1 foot is 1/8 inch
To convert from foot to inch, we multiply by 1/8
To convert from inch to foot, we multiply by 8
Thus, we have ;
Let’s fill in the left spaces first;
6.25 * 8 = 50 feet
Right spaces, top to bottom;
128 * 1/8 = 16 inches
80 * 1/8 = 10 inches

Point A is located at -4.5, and point B is 3.25 units from point A. Write two additional equations that could be used to determine the location of point B.
Answer:
The equations are B = -4.5 + 3.25 and B = -4.5 - 3.25
Step-by-step explanation:
Since point A is located at -4.5 and point B is 3.25 units away from A, point B can either be located on the left or on the right of point A.
If point B is located at the right of A, the equation for point B is -4.5 + 3.25.
If point B is located at the left of A, the equation for point B is -4.5 - 3.25.
So, the equations are B = -4.5 + 3.25 and B = -4.5 - 3.25
State the slope and y-intercept of y=5x+2
Answer:
5 is the slope
(0,2) is the y intercept
Step-by-step explanation:
The equation y = 5x + 2 appears to be written in the y = mx + b form of a linear equation.
m represents slope and b represents the y value of the y intercept.
Here, m = 5 and b = 2.
This means 5 is the slope and (0,2) is the y intercept.
Graph both equations. What point do they intersect at?
y = x + 3
y = -x-1
Answer: y= -1-1 = (0,-1) y= x + 3=(0,3)

Triangular numbers can be represented with equilateral triangles formed by dots the first fire triangle numbers are 1 3 6 10 and 15 is there a direct variation between a triangle number and its position in the sequence explain your reasoning
Answer:
There's no direct variation
Step-by-step explanation:
Required
Determine if there's a direct variation between the number and its position
I'll start by giving an illustration of how the triangle is represented using stars (*)
*
**
***
****
*****
Represent the line number with y and it's position with x
On line 1:
y = 1, x = 1
On line 2:
y = 2, x = 3
On line 3:
y = 3, x = 6
On line 4:
y = 4, x = 10
On line 5:
y = 5, x = 15
Note that, x is gotten by calculating the accumulated number of stars while y is the line number.
Direct variation is represented by
y = kx
Or
kx = y
Where k is the constant of variation
For line 1:
Substitute 1 for y and 1 for x
k * 1 = 1
k = 1
For line 2:
Substitute 2 for y and 3 for x
k * 3 = 2
Divide through by 3
k = ⅔
Note that the values of k in both computations differ.
This implies that there's no direct variation and there's no need to check further.
hi, can someone please help me with this. will give brainliest.
Answer:
It will be a positive sign.
Step-by-step explanation:
Since the exponent is an odd number, the base is going to keep the same sign. Then, since you are dividing a negative number by a negative number, you will get a positive number.

Katie has f fish. Alejandro has 11 fish, which is 3 fewer than twice the number Katie has.
Which equation shows an equality between two different ways of expressing how many fish Alejandro has?
A. f + 3 = 11
B. f – 3 = 11
C. f/2 - 3 = 11
D. 2f – 3 = 11
Answer:
The answer would be D
Step-by-step explanation:
To find how many Katie has, you would have to double it ( times by 2 ). Then subtract 3, since Alejandro has three less than twice as many as Katie.
Answer:
the answer is d just did the test got it right

On average, Americans consume 13.9 pounds of ice cream per person over an entire year. Ben loves ice cream, but limits himself to one 6 ounce (oz) serving each week. Find the difference between the amount of ice cream that Ben consumes compared to the national average.
Answer:
5.6 pounds
Step-by-step explanation:
13.9 pounds of ice cream are consumed per year by individual.
Ben consumes 6 ounce serving per week.
The amount of ice cream consumed by Ben in a year can be determined by;
since there is an average of 52 weeks in a year, then;
6 ounces x 52 = 312 ounces
But,
1 ounce = 0.0625 pounds
So that,
312 ounces = x pounds
x = 312 x 0.0625
= 19.5
x = 19.5 pounds
Thus, Ben consumes 19.5 pounds of ice cream per year. He consumes more than the average value per person in a year.
The difference = Amount Ben consumes - National average
= 19.5 - 13.9
= 5.6 pounds
What is an equation of the line that passes through the point (6, 1) and is
perpendicular to the line 2x + 3y = 18?
Answer: y=1,5x-8
Step-by-step explanation:
At first transform the equation
2x+3y=18
3y= 18-2x
y= 6 - (2/3)x
The linear function has general form, which looks like that:
y=mx+n
perpendicular means that m1*m2=-1
In our case m1= -(2/3) and m2 is unknown
(-2/3)*m2= -1
m2=3/2 so m2=1,5
The line has to go through the point (6,1)
so 1=6*1,5+n
1=9+n
n= -8
so the function looks like that y=1,5x-8

What is an ordered double?It is defined as a representation of coordinates in a two-dimensional coordinate plane. It has a list of two elements in it, such as (x, y).
The area using the ordered double:
[tex]\rm Area = |\dfrac{(x_1y_2-y_1x_2)+(x_2y_3-y_2x_3)....+(x_ny_1-y_nx_1)}{2}|[/tex]
As we know the coordinate plane is divided into four parts.
The first part is known as I quadrant; in this quadrant both values of x and y are positive.
In the second quadrant II value of x is negative and the value of y is positive.
In the third quadrant III values of x and y are negative.
In the fourth quadrant IV value of x is positive and the value of y is negative.
From the above information:
The point (5, 5) is in Quadrant I
The point (3, –2) is in Quadrant IV
The point (–4, –4) is in Quadrant III
Thus, the point (5, 5) is in Quadrant I, the point (3, –2) is in Quadrant IV, and the point (–4, –4) is in Quadrant III.

3) A product is marked down 15%; the sale price is $127.46. What was the
original price?
Answer:elling price (S.P) = (100 - m)% ⋅ Original price -----(1)
Here,
S.P = 127.46, m = 15
Substitute 127.46 for S.P and 15 for m in (1).
127.46 = (100 - 15)% ⋅ Original price
127.46 = 85% ⋅ Original price
127.46 = 0.85 ⋅ Original price
127.46 / 0.85 = Original price
149.95 = Original price
So, the original price is $ 149.95.
Step-by-step explanation:
The original price of product when the product is market down by 15% and the sales price is given so it is $149.95.
Calculation of price:Price is down by 15%, so m = 15% or 0.15.
So, Original price = [tex]\frac{Selling price}{( 1 - m)}[/tex]
By putting the value, we get
Original price = [tex]\frac{127.46}{(1 - 0.15)}[/tex]
= [tex]\frac{127.46}{0.85}[/tex]
= $149.95
Hence the original price of of the product was $149.95
